Hope someone can help me solve an issue that I have with my home LAN. The setup is as follows: 1) DELL XPS 600 with NForce 1Gb NIC - Windows XP Professional 2) DLink 1Gb switch but have tried also a Netgear 1Gb switch that I purchased for the purpose. 3) Terastation Home Server 2Tb with 1Gb NIC and FTP server enabled 4) Cat. 6e Mattroxx cables newly purchased 5) Latest drivers and software all around 6) Am using and have configured Norton Firewall but even with this disbaled the issue is still present. I have only TCP/IP enabled. The switch confirms that all connections are 1Gb. Link is set at 1Gb full duplex, confirmed on both the PC and the NAS unit. Drives are all fast 7200 latest generation SATA drives in the PC and RAID5 IDE drives in the Terastation. All cables are less than 1.5m (5'), long, brand new and Cat. 6e. I am moving large video files (3Gb to 6Gb). Using an FTP client (CuteFTP), moving data from the Terastation into one of the drives of the PC (no overhead from parity calculation in the RAID5), I can get a maximum of 120Mbps no matter how many transfer threads I initiate (i.e. if I transfer 5 files, the 120Mbps is equally divided between them). Using Windows Explorer to transfer files, speed is even lower. I expect this type of connection to yeld more than 120Mbps but for the life of me I cannot find any further setting to tweak to increase performance and I am particularly puzzled by the staticity of the maximum transfer speed regardless of the number of files being transferred. Transfer between drives on the PC moves files at much greater speed, hence the limiting factor is not drive speed. Could anyone help me with some further idea on what to look for? I tried downloading WireShark but it goes beyond my knowledge and is not helping... Thank you in advance for any help that could be kindly extended. Best regards. Massimo.
